CD4047BF Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for the CD4047BF?
  The recommended operating voltage range for the CD4047BF is 3V to 15V.
• How do I ensure the oscillator circuit is stable and reliable?
  To ensure a stable and reliable oscillator circuit, use a high-quality capacitor with low equivalent series resistance (ESR), and keep the layout as compact as possible to minimize parasitic inductance and capacitance.
• What is the maximum frequency of operation for the CD4047BF?
  The maximum frequency of operation for the CD4047BF is approximately 1 MHz, but this can vary depending on the specific application and component values.
• Can I use the CD4047BF as a voltage-controlled oscillator (VCO)?
  Yes, the CD4047BF can be used as a VCO by applying a control voltage to the threshold input (pin 9) to vary the oscillator frequency.
• How do I synchronize the oscillator output with an external clock signal?
  To synchronize the oscillator output with an external clock signal, connect the external clock signal to the sync input (pin 10) and ensure the clock signal is within the specified frequency range.
